Abstract

Aiming at the current bar cutting machine there are problems such as workpiece clamping is not firm and low machining accuracy, this paper proposes a cutting machine improvement method. First of all, based on solidworks software for three-dimensional modeling, the mechanical structure design of bar fixture, cutting blade, guide rail, frame structure. And finite element analysis was used to simulate the working condition of the bar fixture machining process, and the results show that the V-shaped fixture reduces the positioning error and improves the stability of the bar position and the machining accuracy of the workpiece. The bar cutting machine designed in this paper can enhance the stability of the bar position and the quality of bar cutting in the cutting process.
